The upgrade items aren't apart of the weekly lockout either so you don't have to choose between the Ironwork's equivalent of Sands of Time or a piece of gear.
Yeah, I was surprised they included her in the trailer, I thought they'd make us wait until the patch lands to see her face.
The bard gear is the nicest I think, I'm not sure which set I'll pick up first between the two. I won't get the healer gear since I've nearly gotten a full set of Ironworks healing gear already.
My guess is that the gear will drop in the new dungeons since Soldiery tomes won't be removed until the next major patch so they won't be loot just yet.
